Polarization of Light

Polarization of light refers to the direction in which light waves oscillate as they travel. Normally, light waves vibrate in many directions, but when light is polarized, these vibrations are restricted to a single direction. This can occur naturally, like when sunlight reflects off a surface, or artificially, through polarizing filters. Polarized light is useful in many applications, such as reducing glare in sunglasses, enhancing contrast in photography, and improving visibility in LCD screens. Understanding polarization helps us better control and utilize light in technology and our daily lives.
